(CNN)A prominent Saudi activist's admission that she once applied for a job at the United Nations is being used as part of the kingdom's case against her, CNN has learned.

Saudi Arabia has not publicly released the charges against women's rights defender Loujain al-Hathloul, or several other prominent female activists who are currently on trial in Riyadh on charges related to their human rights work.

But in a six-page charge sheet for Hathloul's case, seen by CNN, a section titled "crimes committed" includes activism against the kingdom's restrictive male guardianship laws, along with contact with foreign journalists and diplomats.

The charges rely on a series of alleged confessions, according to the documents, which state that Hathloul confessed to applying for a job at the UN along with confessing to being in contact with the human rights groups Amnesty International and Human Rights Watch.

Hathloul applied to the UN's Young Professionals Programme in 2017, her family members told CNN.

Hathloul's family members said she has reported being physically and sexually abused in detention. During a visit to the prison by her parents, she told them that she was regularly whipped, beaten, electrocuted and sexually abused in a basement she called the "palace of terror," her brother, Walid al-Hathloul, wrote in a CNN opinion piece in January.
